Summary
The Microchip's ARM-based SAM7X512 is a member of the Microchip SAM7X series of microcontrollers based on the 32-bit ARM7TDMI processor. It operates at a maximum speed of 55 MHz and features 512KB of flash memory and 128KB of SRAM. The 512KB of flash are split in two banks of 256KB. The peripheral set includes USB 2.0 Full Speed device port, Ethernet MAC 10/100Base T port, CAN 2.0A and 2.0B compliant controller, two USARTs, UART, two SPI, SSC, TWI (I2C), three 16-bit timers, RTT and 8x10-bit ADC. Typical core supply is 1.8V, I/Os are supplied at 1.8V or 3.3V and are 5V tolerant. An integrated voltage regulator allows single supply at 3.3V. The SAM7X128 is supplied in 100-lead LQFP and TFBGA packages.
